Hooves are read as solid footing, progress and the sound of something approaching. The beat of hooves in a dream is often taken as news or change on its way.
Does the traditional reading fit your dream, or did it mean something else to you?
My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
